Please notice that the crystal oscillator should be fully turned off before entering the power-down mode, in
order to avoid unexpected wakeup event. If the 32KHz crystal oscillator is used and extremely low operating
current is required, misc.6 can be set to reduce current after crystal oscillator is running normally.
5.7.5. System Clock and LVR levels
The clock source of system clock comes from EOSC, IHRC and ILRC, the hardware diagram of system clock
in the PMC271/PMS271 is shown as Fig. 9.
Fig. 9: Options of System Clock
User can choose different operating system clock depends on its requirement; the selected operating system
clock should be combined with supply voltage and LVR level to make system stable. The LVR level will be
selected during compilation, and the lowest LVR levels can be chosen for different operating frequencies.
Please refer to Section 4.1.
